[Rebranding Announcement] Entertainment App "Kara Kyas" with Over 300,000 Registered Users Rebrands to "Charaful". Evolving into a Next-Generation Platform for Connecting Individual Personalities to Corporate Marketing Value, Championing the Concept of "Human IoT" in the AI Era.

Colorful Casting Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Toyoki Matsumoto) is pleased to announce that the service name of its next-generation entertainment app "Kara Kyas," which has over 300,000 registered users, will be changed to "Charaful" effective July 1, 2026.

In conjunction with this change, we aim to further accelerate influencer marketing in anticipation of the AI era and evolve into a two-way platform where not only creators but also general users can leverage their talents and personalities to create new touchpoints and experiential opportunities with companies and brands. To achieve this, we will implement new features and launch large-scale SNS promotions.

Background of the Service Name Change and the Meaning Behind "Charaful"

To date, our company has supported corporate marketing DX and the expression of individual talents and personalities through "Kara Kyas," an entertainment app that connects companies and individuals, and individuals and fans, centered around "profiles."

"Kara Kyas" is utilized by many companies as a matching platform connecting diverse users, including influencers, models, actors, artists, and general consumers, with companies. It has also been cherished by our users as a place to express their personalities and leverage their talents and interests. Thanks to their support, our registered user base has surpassed 300,000.

Currently, with the rise of generative AI, consumers' information discovery and purchasing behaviors are undergoing significant changes. The value of reliable UGC (User Generated Content) in the digital space, as well as the individual personalities, interests, and behavioral data of each consumer, is increasing more than ever.

In this AI era, our company aims for a world of "Human IoT" that visualizes each person's unique personality (character) digitally and connects them with companies, brands, fans, and society.

This rebranding goes beyond a mere casting service; it aims to realize a society where the personality of each user and consumer creates new touchpoints with companies and brands, leading to experiential value.

Furthermore, we aim to evolve into a platform that allows companies to accelerate fan building and brand value enhancement through co-creation with consumers who possess passionate personalities.

The new name "Charaful" embodies our desire for a service where various "characters" and "personalities" gather, and each of their possibilities unfolds colorfully.

Moving forward, our company aims to be the "No. 1 App for Personality (Character) Registrations," broadly visualizing the potential for new work, encounters, support, and challenges by expanding the possibilities of everyone's inherent personalities and charms.

Under the mission of "A world rich in personality (Charaful) where all personalities (characters) shine abundantly (full)," we have decided on this rebranding to expand a world where personalities create new value for both users with diverse personalities and talents, and companies.

Two Values Brought by the New "Charaful"

1. For Companies: Accelerating Influencer Marketing to Be Chosen in the AI Search Era

We maximize engagement with our SNS data analysis platform covering over 190 countries worldwide (over 200 million people) and our more than 300,000 registered users. We provide evidence-based visualization of deep resonance with brands, not just superficial numbers, and powerfully support the rapid construction of trusted brand assets (UGC) in the AI era.

2. For Users: Creating New Experiential Opportunities by Leveraging Personalities

With the implementation of new features, we will provide a system where not only creators such as influencers and artists, but all consumers can connect with companies and brands by leveraging their "own character (personality, talent, hobbies, preferences)" and gain new experiential opportunities and participation value through experiential events, limited gifting, and more.

Future Outlook: Implementation of New Features and SNS Promotion Rollout

In conjunction with the rebranding, we will sequentially implement update features to further deepen matching and engagement between companies and users.

Furthermore, we will sequentially launch large-scale SNS promotions to commemorate this rebranding. We will create a space for communication where companies and users can share experiences as one and enjoy two-way interaction as a digital "festival."

Comment from Representative Director Toyoki Matsumoto

"Kara Kyas" has achieved significant growth with the support of many users and companies. The advent of the AI search era further enhances the "value of individual trust" that we have advocated. The new name "Charaful" embodies our intention to create a society where everyone can live richly by leveraging their own color (character). As pioneers of "Human IoT," we will provide companies with a marketing space free from uncertainty and offer consumers a space that makes their daily lives more enjoyable and fulfilling, thereby building an unprecedented two-way entertainment society.
